I am looking for a software that will let me record my voice and create a video with visualizer (correct me if my choice of words is wrong) that is sensitive to my voice like TV professionals show on screen when they do not have a video footage to go with it. A wave that moves up and down when the person is speaking and comes to rest when there's no audio activity.
Here's an example of what I want as the end product (see how it's jumps only when the music is playing):
but a lot more formal and preferably in the form of waves.
I'd like the piece of software to be able to take in sound in the form of a .aac or .mp3, and output the video in .avi, .mp4, or .avi. I'm quite flexible with the format, though, and I'm happy to convert files between formats.
I use Windows, OS X, and Linux, so OS isn't really a problem.
